Abstract
A method for establishing a sprayable stream of composite material for spray-applying to a target surface to create thereon a defined composite-material coating designed for defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character, where the target surface is on a side of that wall. The method includes (a) initiating a pair of respective sub-flows of two, precursor elastomeric materials intended for later blending to create a formed, elastomeric body, (b) at a point downstream from such initiating, introducing a flow of plural, liquid-imbiber beads which are reactive to the mentioned, particular-character liquid, (c) in a user-chooseable manner upstream from where such later blending takes place, merging the flow of beads with at least one of the two sub-flows of elastomeric materials, (d) following such merging, blending the two sub-flows, and (e) thereafter spray-applying the merged and blended flows/sub-flows to a target surface thus to create the desired, defined composite-material coating.
